For Bilinsky, the opportunity in setting up a business exclusively focused on filling prescriptions means reduced prices and better options for the estimated 188.7 million people who wear corrective eyewear or contact lenses in the U.S.

“We’re offering every different type of prescription lens for every different frame brand,” says Bilinsky. “[We’re] mimicking what a customer can do going into a LensCrafters at up to 70 percent cheaper than a traditional provider.”

And given the changing ways in which glasses buyers are shopping for frames, launching a business that caters to providing the right lenses at a lower price makes sense, Bilinsky says.

“With Amazon becoming the largest individual reseller of eyewear in the U.S., every frame that people buy that needs to be re-lensed. It’s a secondary market in the same way that you would put new rims on the car,” says Bilinsky.

Lensabl offers about 400 different permutations of lenses and 20 different tint colors. “It’s a customization platform for your frames,” says Bilinsky.
